Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting oil heating, in particular to a cyclically used heat-conducting oil heater. Background Art

[0002] Chlorotrifluoroethylene, also known as chlorotrifluoroethylene, is one of the important monomers for synthesizing fluorine-containing materials. It can be used to produce fluororesins, fluoro coatings, fluororubbers and chlorofluoro lubricants through homopolymerization and copolymerization. These materials have good chemical inertness and high temperature resistance and are widely used in cutting-edge technology, military navigation and the electronics industry. The production of chlorotrifluoroethylene using trifluorotrichloroethane as raw material includes two main process routes: trifluorotrichloroethane zinc powder reduction dechlorination method and trifluorotrichloroethane gas-solid phase catalytic hydrogenation dechlorination method. The gaseous trifluorotrichloroethane gas-solid phase catalytic hydrogenation dechlorination method is relatively simple. The gasified trifluorotrichloroethane is mixed with hydrogen and catalyzed by a specific catalyst to produce trifluorochloroethylene. A reactor is required for the preparation of trifluorochloroethylene by hydrogenation dechlorination of trifluorotrichloroethane. In order to reach the temperature required for the reaction of the raw materials, heat transfer oil is usually used to circulate the reactor for heating. The heat transfer oil circulation heating method is widely used in the production process due to its high thermal efficiency, uniform heating and low overall cost.

[0003] For example, a Chinese utility model patent with authorization announcement number CN218945040U discloses an automatic temperature control device for a heat transfer oil circulation heating reactor, comprising a heating furnace, an oil bin installed on the heating furnace, a circulating oil pipe connected to one side of the oil bin, a first connecting pipe connected to one side of the circulating oil pipe, a circulating heating jacket connected to one end of the first connecting pipe, a connecting frame installed on the top of the circulating heating jacket, a temperature measuring seat connected to the top of the connecting frame, a temperature sensor installed on the bottom of the temperature measuring seat, an insulating outer ring connected to the outside of the circulating heating jacket, an insulating pad connected to the outside of the insulating outer ring, a plurality of inner grooves provided in the middle of the inner wall of the insulating outer ring, an installation frame connected to the middle of the inner groove, a micro-heating plate installed inside the installation frame, the utility model provides an automatic temperature control device for a heat transfer oil circulation heating reactor, reduces heat loss, assists in heating the circulating heating jacket, ensures the temperature of the heat transfer oil inside the jacket during the heating process, and improves the continuous heating effect of the reactor by the entire device.
